Returning a downloadable file using a stream in asp.net web forms

Question

In asp.net MVC I can do something like the following which will open a stream:

 Stream strm1 = GenerateReport(Id);

return File(strm1, 
            \"applica         


        

Answer 1

I use this extension to send a stream as a downloadable file:

public static class ToDownloadExtention
{
   public static void ToDownload(this Stream stream, string fileName, HttpResponse response)
    {
        response.Clear();
        response.ContentType = "application/octet-stream";
        response.AddHeader("Content-Disposition", string.Format("attachment; filename={0}", fileName));
        stream.CopyTo(response.OutputStream);
        response.End();
    }
}

And the usage is:

var stream = new MemoryStream();

stream.ToDownload("someFileName.ext",Response);
